Snow Village

Expert Review

For the coolest night of your life, sleep on a slab of ice (topped by a thermal sleeping bag, of course) inside a massive igloo at the Snow Hotel. Open December to April, the Snow is completely reconstructed each winter and offers seasonal excursions like dog sledding and snowmobiling. Mixologists take note: It also hosts the Finlandia Vodka Cup bartending competition every February.
